Abstract
A method and apparatus to simulate arterial blood pressure pulses to train clinicians in the use of oscillometric blood pressure monitors is described. The apparatus comprises a bladder or blood pressure cuff placed in a rigid enclosure with a known volume. The enclosure also has an opening, with a pressure plate placed between the opening and the bladder. An actuator, such as a servo motor with an arm, is attached to the outside of the enclosure next to the opening such that the arm of the servo motor or actuator may exert a force on the pressure plate, which in turn impinges the bladder. The bladder may be connected to a pressure sensor and an oscillometric blood pressure monitor. The force exerted by the actuator may be controlled in a feedback loop by a controller connected to the actuator and the pressure sensor.
